From Salt article: We would typically complain these population-level averages are just that and along with all averages, are a convenient oversimplification which in no way applies to significant parts of the population (no-one actually has 2.4 children). However, in this case, the minimum amount of sodium the human body requires on a daily basis seems to be around 0.5g or less, so this recommendation seems likely to cover a larger majority of the population than most. This is supported by the fact the recommendation is a maximum (rather than an amount or minimum as most are) which also would appear to demonstrated the seriousness with which the risks of overconsumption are treated within the medical field.
